Description

Technical Field

[0001] The utility model relates to the technical field of metal piece processing, in particular to a metal piece welding assembly for a pneumatic welding machine. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Electric welders are important equipment in the welding process. They have the characteristics of high production efficiency, low cost and easy automation. Therefore, they are widely used in various industrial sectors such as aviation, aerospace, energy, and light industry. It is one of the most important welding processes.

[0003] However, when some existing metal welding assemblies are put into use, they all weld the surface of the metal parts by pressing down on the welder. However, most welding assemblies require workers to manually process the metal parts at the bottom of the welder. Since the welder exerts a certain force on the metal parts during the downward pressure processing, the metal parts may shake, thereby reducing the processing effect of the welding assembly on the metal parts.

[0004] At the same time, most pneumatic welding machines for metal parts welding components need to weld multiple locations on the surface of the metal parts. Since the workers manually move the metal parts, the positions moved manually by the workers are not accurate enough, which will lead to inaccurate welding processing. Utility Model Content

With the cooperation of the first rotating rod 6 and the second rotating rod 7, the moving mechanisms 9 on both sides can work at the same time, so that the moving mechanisms 9 can clamp the metal parts, effectively preventing the vibration of the welding body 3 when processing the metal parts frame, increasing the stability of the assembly, thereby increasing the metal parts. Processing effect, the surface of the fixed shell 4 is bolted with a support frame 10, one side of the workbench 2 is bolted with a mounting plate 13, the top of the mounting plate 13 is bolted with an electric telescopic rod 11, the output shaft of the electric telescopic rod 11 is fixed with a fixed block 12, the top of the fixed block 12 and the bottom of the support frame 10 are bolted to each other, with the cooperation of the electric telescopic rod 11 and the fixed block 12, the support frame 10 can be driven by the mobile mechanism 9 to move through the fixed shell 4, so that the component can process metal parts more accurately, effectively preventing the staff from manually adjusting the position inaccurately, thereby improving the processing effect of the component on the metal frame The surface of the first rotating rod 6 is rotatably connected to the fixed sleeve 8, and the surface of the fixed sleeve 8 is bolted to the surface of the support frame 10. Under the action of the fixed sleeve 8, the first rotating rod 6 and the second rotating rod 7 are effectively prevented from positional displacement during operation, thereby increasing the stability of the first rotating rod 6 and the second rotating rod 7, thereby increasing the stability of the assembly. A guide mechanism 14 is provided above the mounting plate 13. Under the action of the guide mechanism 14, the fixed shell 4 can be effectively prevented from positional displacement during operation, thereby increasing the stability of the fixed shell 4, thereby increasing the stability of the assembly.

Then, the staff uses the electric telescopic rod 11 to make the fixed block 12 drive the fixed shell 4 to move through the support frame 10, so that the fixed shell 4 can move the metal workpiece at the bottom of the welding body 3 through the clamping plate 93. At the same time, the support frame 10 makes the guide block 143 move in the inner cavity of the guide groove 142 through the connecting rod 141, so that the fixed shell 4 can move more stably, and under the action of the electric telescopic rod 11, the distance moved by the metal workpiece is more determined.
